Zusammenfassung
Da Testosteron eine entscheidende Rolle beim Verlauf von benignen und malignen Prostataerkrankungen spielt, sind die physiologischen Interaktionen von Testosteron und Prostatagewebe und die Besonderheiten der Hormonersatztherapie bei Patienten mit Prostataerkrankungen für praktisch tätige Urologen von entscheidender Bedeutung.
Unter einer Testosteronsubstitutionstherapie zeigen sich keine signifikanten Veränderungen des PSA-Werts bzw. des Prostatavolumens. Obwohl Langzeituntersuchungen an Männern mit einem Androgendefizit fehlen, erscheint eine Testosteronsubstitution unter regelmäßiger Kontrolle der Prostata mittels Sonographie und PSA-Wert möglich und die Gefahr der Induktion eines Prostatakarzinoms nicht erhöht.
Bei hypogonadalen Männern mit nachgewiesener „High-grade-PIN“ trat unter der Testosteronsubstitution im Beobachtungszeitraum in 1/20 Fällen bei suspektem Tastbefund ein manifestes Karzinom auf, die PSA-Werte zeigten keinen Unterschied zwischen Patienten mit und ohne PIN.
Dennoch bleibt es unklar, ob eine Testosteronsubstitution nach erfolgreicher radikaler Prostatektomie durchgeführt werden soll.
Abstract
Testosterone has a distinct role in benign and malignant diseases of the prostate. Therefore, knowledge about the physiological interactions between testosterone and the prostate and the special circumstances under testosterone substitution are of great impact for urologists.
PSA value and prostate volume do not show significant changes under testosterone substitution therapy. Even if there are no long-term studies in men under substitution due to decreased testosterone, the therapy seems to be safe under regular control of the prostate with PSA and sonography, and the risk for prostate carcinoma is not increased.
In hypogonadal men with high-grade PIN under testosterone substitution, 1 in 20 cases with suspicious rectal examination exhibited a carcinoma; the PSA values did not show a difference between men with or without PIN.
Nevertheless, it remains unclear whether men after successful radical prostatectomy should receive testosterone substitution.
